INTERLOCK'ING TILE.

ll) aZZ whom it may concern:

lle it known that l, Janus J, l uus'rnn, a citizen oithe United States, residing H1 the city and county of San Francisco and State (ill California, have invented new and useful improvements in interlocking 'liles, of which the zliollowing is a specification.

liiv invention relates to an interlocking and intcrbonding tile, and to a means for uniting such tiles to a wall or other surface, so as to make a strong integral structure without other aid. It also enables the walls and tiles to be laid simultaneously and the entire structure to be completed in a single (fiiitllllifillfi operation.

The invention includes details of construction which will he more fully explained by reference to the accompanying drawings in whichl igure l is a perspective view of a wall and tiles. Fig. 2 is a horizontal section of a portion elf a wall with attached tiles. Fig. ii is an elevation of the device with vertical tilesv In structuresconsisting of walls or their equivalents and' supplemental surfacing tiles, various iucthods have been employed to secure such structural elen'ientstogether. in this invention l, unite the parts securely and rapidly withoutthe use of connecting rods or other extraneous means.

as shown in the drawings, A represents a section wall which may be hollow with interconnecting ribs or, or it may be of brick or other 'iaterial laid up in solid form The surtace to which the tiles are to be attached is formed with keys of dovetailed or other suitable form grooved or corrugated on their outer faces. These keys are here shown as being disposed vertically and continuous to form a convenient means for the attachment of the tiles 3. These tiles may be of anv suitable iorin or size and are provided, on the fares contiguous to the wall, with l ev-ways separated by grooved which are dr esigned to interlock withthe kcvs l so'that they may be laid and fixed siiiiull'ancously with the laying up of the wa l. lhis interlocking bond may be on one or all sides or the back. T he facing material is preferably so laid with reference to the back as to overlap the joints of tie latter. and thus form an interlocking bond. it will he obvious that any desired'inaterial, color, texture, or linish may be en'ipioyed,

and the surfaces may be vitrified or glazed, corrugated or plain. While this construction forms a con'iplete bond by reason of the interlocking keys and webs, the union is rendered more complete and the entire structure made integral and solid by a suitable mortar spread between the meeting parts. By this construction a horizontal as well as a vertical bond and union is effected, and the whole wall and facing completed at a single ope 'ation and without the use of ties of any description.

The ends of the tiles meet at such points as to break joints with or meet intermediate of the edges of the wall blocks, opposite a key channel therein, and each end of a tile has a half web P formed upon it so that when the webs of two meeting ends are inserted in the contiguous key channel, the latter will be filled by and hold the tile ends together. The facing tile will also act as a tie for the wall block. These tiles may be built with the webs and chambers reversed so that the keys of the wall run horizontally and the Webs of the surface tile run vertically, as shown in Fig. 3.

Having thus described my invention, wl'rat I claim and desire to secure by Letters Patent is- A wall structure comprising a plurality of blocks each having a plurality of dovetailed keys provided with series of dovetailed grooves and interposed by similarly shaped key ways and having end way portions adapted to be supplemented by those of the adjacent blocks to form sectional dovetailed key ways, the adjacent opposing faces of the ad acent blocks being spaced and provided with coincident dovetailed grooves, a tiling surface composed of tiles each of which. is provided. with a dovetailed web received in a sectional key way of the block portion of the wall and hav ing a dovetailed groove arranged in its outer face opposite the space between the opposing faces of the adjacent block memlib hers whereby a tiller of cement will inter lock in the groove of the tile web and also in the co1nc1dent grooves of the opposing faces of ad acent blocks to withstand movement tending to. separate the tile from the blocks, each tile being further provided on. its ends with a web section adapted to be supplemented by the end web section of the adjacent tile to form a complete dovetailed lull Web, said sectional dovetailed Web being received by a key Way of a block member and of smaller cross sectional area than the Way, 'the Ways formed by and between the dovetailed web and the end Web sectioris of each tile receiving the block keys and provided with dovetailed grooves 0pposing the grooves of the block keys, and a fillingof cementinterposed in the space be- 10 tween adjacent block members, adjacent tiles and the channels around the sectional Webs and solid webs.

In testimony whereof I have hereunto set .my hand in the presence of two subscribfmg Witnesses.
